I don’t know that answer and neither does anybody else since the vaccine has been in operation for less than 3 months.
However 55+ MILLION Americans have already been vaccinated. That is an astronomically big sample. If there are mass deaths related to the vaccine, it will be very difficult to hide that news. My guess is we will know soon.
And I am trying to search how many of those 55 million inoculated with vaccine have died. Not found that answer yet.
